Great Isle is the name of one of the Predesigned maps that are downloadable with the free game C-evo. Quite large at "375% size", it allows the standard number of players (15). Because there are 24 possible Starting Positions fairly evenly spaced around a large, almost circular, island, a player may find several very close rivals or find sparse areas capable of almost uninterrupted colonization for a few centuries. A further non-standard feature is that there is no Mercury, so you cannot score a proper win by building a spaceship.
